摘要
Abstract
In order to move the pendulum rod by electromagnetic control according to the specified angle and period,a mi-crocontroller STC89C52 is used as master chip,a digital three-axis angle sensor ADXL345 is employed to detect the pendulum angle in real time,the adaptive algorithm is adopted to calculate the time required for the pendulum rod's swing,and the driving module L298N is selected to control the solenoid by PWM pulse signal. Furthermore,LCD12864 liquid crystal display is chosen to show the default parameters. The testing results show that the absolute error of the pendulum rod swing angle is ≤1° ,the maximum response time to start is ≤9 s,and maximum response time to stop is ≤10 s.关键词
